Edit:
The seller Yospace had written to me because of my review and was very concerned that problem to solve with the dust. I have (the New Upgraded version) now get a new Stylus sent. The first time you tap the screen dust could be seen again but after a few other predictors was nothing more to see. I am now fully satisfied with the stylus.
Edit2:
After about 3 months using the stylus, the sensitivity declines significantly. I need to tap several times and often with a lot of pressure before the tablet responds. Therefore, now only 3 stars.
